Cigars 4 are packaged in cartons 7 supplied from a magazine 6 by a reciprocable plate 8, which also erects the cartons against a movable stop 8b, a switch 11 operated by the cartons and a switch 5 operated by the cigars being connected in series so that a piston 22 is not actuated to feed the cigars forward unless an erected carton is in position to receive them. Each carton 7 is pushed up spring fingers 6a, Fig. 3, until the forward edge of the carton engages under a plate 10a secured to a piston assembly 9, the carton being erected against the action of the fingers 6a. The filled carton is fed forwards by a piston assembly 26, the assembly 9 including the stop 8b being raised. Spring-loaded pawls 29 on a carriage 28, driven by the assembly 9, transmit the carton to position 7b, the pawls 29 being in four pairs to enable further indexing of the carton to positions 7c-7e. Pairs of spring- loaded pawls 30 retain the carton in each position. As the carton moves forward, the flap 12 is folded by a set of plates 44, and one of the carton bottom flaps is folded by a plate 45, the second bottom flap being glued by a wheel 47 before folding by a plate 53. Pressure is applied to the closed carton in a section 54, a wall 56 being advanced pneumatically when a carton touches a switch between positions 7d and 7e. A piston assembly 65 pivots upwards a cruciform plate 63 as the switch 63 is closed. Side walls 78, 79 have inwardly-directed bristles to keep the cartons upright.

Abstract: 279,983. Thompson, T. Sept. 8, 1926. No Patent granted (Sealing fee not paid). Baffles.-A fitting of the kind which is placed in the uptake flue of a range to deflect the gases against the rear wall of the boiler comprises an easily removable deflector or plate 6, 7 with a base 5 adapted to rest on the bottom of the flue to support it in a substantially vertical position. As shown in Fig. 1, the plate comprises a rearwardly-inclined lower part 6 and a forwardlyinclined upper part 7, forming, with the rear face of the boiler, a passage of upwardly-diminishing section. Positioning-lugs 16 at the top of the plate contact with the rear face of the boiler. A central vertical rib 13a with inclined faces deflects part of the gases laterally, the lower end being extended to form an apertured lug 14 for engagement by a suitable implement. Additional securing-means for the fitting may be provided that shown comprising a rod 19 with an expansion loop 21 pivoted to it and engaging the rear wall of the flue. In the modification shown in Fig. 4 the fitting is made in two parts, the lower part 22 being of semi-circular shape and the engaging faces 23 of the two parts being bevelled. A dovetail rib and groove 24 connects the two parts, the arrangement allowing the lower part to be drawn out through the boiler flue and the soot deposits behind the plate to be removed through the aperture thus left in the upper part. In a further modification the upper part of the plate is curved in vertical section and the top edge rests against the boiler. The gases escape through an aperture near the top of the plate and beneath a short hood extending rearwardly from the top edge.

IPC: B60J7/20
Filed: 1951-09-24
Abstract: 711,975. Hydraulic machines; fluid actuated valves. SMITH'S JACKING SYSTEMS, Ltd. Sept. 16, 1952 [Sept. 24, 1951], No. 22279/51. Classes 69 (2) and 135 A hydraulic control apparatus comprises a main differential area piston jack, an auxiliary jack having inlet and output ports arranged to intercommunicate when the auxiliary jack is fully extended whereby the main jack is supplied with pressure fluid, and solenoid. actuated valves to control the operation. A pump 12 driven by an electric motor 13 controlled by a solenoid actuated switch 38 draws from a reservoir 10 and delivers pressure fluid by a line 15, having a normally open bye-pass valve 16 which is closed by the pressure, and a pipe 18 having a pressure relief valve 31, to a jack 33 which operates at a low pressure to lift a spring loaded catch 34. The pipe 18 also feeds a jack 19, the ram of which when it completes its outward stroke connects the pipe to a pipe 22, having a non-return valve 21, leading to one side of a main jack 23. A pipe 29 branches from the pipe 22 to a normally closed solenoid operated valve 26 the other end of which is connected to the opposite end of the jack 23 by pipes 28, 24, the latter being also connected to a second normally closed solenoid actuated valve 25, the other end of which is connected by a pipe 27 to the reservoir 10. The solenoids of valves 25 or 26 are connectible in series with the solenoid of the switch 38 by means of switches 44, 45 respectively. To open the jack 23, switch 45 is closed thereby starting the motor and opening the valve 26. Jack 33 opens followed by jack 19 which supplies fluid to both sides of a differential piston in the jack 23 which is opened and liquid is byepassed to the reservoir through valve 31 until switch 45 is opened. The valve 26 closes and jacks 19 and 33 return under spring pressure, the liquid discharging through the valve 16 which has now opened. To close the jack 23 the switch 44 is closed to start the motor, open the valve 25, open the jacks 33, 19 and supply fluid to one side of the piston of jack 23 while liquid from the other side discharges through the valve 25. The valve 16 comprises a body 90, Fig. 4, having ports 91, 92, 93 connected respectively to pipes 15, 18, 30. A piston 95 is raised by pressure entering the port 91 and carries a member 96 which closes the port 93. The piston is returned by springs 102 and is bored to permit flow to the port 92, the bore being fitted with a restriction 99. A restriction 101 controls the return flow from port 93. The apparatus is described as being suitable for use for actuating a vehicle hood. Specification 655,817 is referred to.

Abstract: 1,169,713. Automatic current control and regulation. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. April 26, 1967 [May 19, 1966], No.22316/66. Headings G3R and G3X. In a control system of the type wherein the inherent regulation characteristic of a transductor 5 maintains constant the current through a variable load 7 (e.g. a number of lamps) over a range of values of the load, the D.C. excitation of the transductor is pre-set in accordance with a signal from a fixed reference source 14 applied to an emitterfollower transistor amplifier 11 controlling the transductor excitation winding 12. Additionally the excitation is made dependent on the output voltage of the transductor to prevent the reduction of R.M.S. current through the load 7 which occurs with increase of the transductor output voltage consequent upon an increase of the load 7 beyond the range, Fig.2 (not shown), this current varying with the form factor of the transductor output which in turn varies with the output voltage. As shown, the transformer 6, 8 supplying the load 7 has an additional secondary winding 9 whose output is rectified to charge a capacitor C1 whose voltage is applied through resistors R4, R6, R7 to the base of a transistor TR1 connected across part of the reference source potentiometer network R1, R2 from which the control signal for the amplifier 11 is derived. In operation, an increase in transductor voltage is reflected through the winding 9 and feedback circuit C1, R4, R6, R7 to make transistor TR1 more conductive and so alter the signal to the amplifier 11, the compensating effect being matched to the transductor characteristic by adjustment of the resistor R5 (which forms with the diode MR2 a non- linear potential divider) and of the tap setting of the resistor R7. A typical compensating effect is described, Fig.3 (not shown).
